Bad Service from Renault Roodeport

I purchased at Renault in Roodepoort 2019.

I took my car twice for service this year, at first it was a faulty battery, now it has sounds when I am driving the car and every time I brake there is a horrible sound which doesn't make sense to me since it's a new car.

Today I took it in for a check up. They tell me this car seems like a 3year old car and has refused to fix it. On the other side they are telling me to pay R3000.00 for it to be fixed.

How can I be paying so much for this car to be fixed where else it's a new car under warranty?

I don't feel safe driving this car because I feel it has too many technical problems or should I say it's an old car.

I am really worried about this matter as I am paying for a new car and I am not happy with the condition of the car.

I refuse to pay for this car any further because R4500.00 for an old car doesn't make sense to me

I am hoping I will get a better offer with this issue because I am really not happy

I have been told to go blame Liquid Capital for this because they paying for the car.

I really don't understand, i am very angry as I don't have a car now and I bought it for my convenience.
